AVBP ArriVent BioPharma Inc

ArriVent BioPharma, Inc. (“Company” or “ArriVent”) (Nasdaq: AVBP), a clinical-stage company dedicated to accelerating the global development of innovative biopharmaceutical therapeutics, today reported financial results for the first quarter ended March 31, 2024, and highlighted recent Company progress.

“In the first quarter of this year, we continued our strong progress as we fully enrolled our NSCLC EGFR PACC mutation Phase 1b cohort in our FURTHER study and initiated a Phase 1b combination study of firmonertinib and ICP-189, a SHP2 inhibitor, in NSCLC patients with EGFR classical mutations. This underscores our comprehensive development plan to maximize the potential of firmonertinib across EGFR mutant NSCLC,” said Bing Yao, Chairman and Chief Executive Officer of ArriVent. “We were also proud to present data at the AACR annual meeting, which further demonstrated that firmonertinib was observed to be broadly active preclinically across a wide range of EGFR uncommon mutations in NSCLC, including PACC and exon 20 insertion mutations. We look forward to continuing building upon these milestones as we work to give cancer patients important new treatment options.”

First Quarter 2024 and Recent Highlights

Firmonertinib

• Presentation of preclinical data for firmonertinib at the 2024 AACR Annual Meeting. ArriVent presented preclinical data evaluating firmonertinib in NSCLC with EGFR exon 20 insertion mutations and P-loop and alpha-c helix compressing (“PACC”) mutations at the AACR Annual Meeting in April 2024. In the preclinical study firmonertinib, a highly brain penetrant mutant-selective EGFR inhibitor, was observed to be broadly active across a wide range of uncommon mutations including PACC and exon 20 insertion mutations.
• Initiation of the Phase 1b combination study with firmonertinib and ICP-189, a novel Src Homology 2 domain containing protein tyrosine phosphatase (“SHP2”) allosteric inhibitor. ArriVent, in partnership with InnoCare Pharma, dosed its first patient in the Phase 1b clinical combination study targeting advanced or metastatic NSCLC patients with EGFR classical mutations, in March 2024.

Upcoming Milestones

• Proof-of-concept data expected in 2024. Firmonertinib is currently being studied in the Phase 1b clinical trial, the FURTHER trial (NCT05364073), in patients with NSCLC EGFR PACC mutations, which has been fully enrolled, with proof-of-concept data expected in 2024.
• Selection of next-generation antibody drug conjugate (“ADC”) development candidate. ArriVent and its partner, Aarvik Therapeutics, Inc., continue to make progress on selecting a multitarget multivalent ADC development candidate, and expect to complete selection in late 2024 or early 2025.

Corporate Updates

• Strengthened board leadership. In April 2024, ArriVent appointed Kristine Peterson to its Board of Directors. Ms. Peterson has served on the boards of multiple public biopharmaceutical companies, including Immunocore and ImmunoGen (recently acquired by Abbvie), and brings over 30 years of industry leadership experience having previously served as Chief Executive Officer of Valeritas and Company Group Chair of Johnson and Johnson for their worldwide biotech and oncology groups.

First Quarter 2024 Financial Results

• As of March 31, 2024, the Company had cash and cash equivalents of $317.4 million, which is expected to fund operations into 2026.   Net cash used in operations was $18.6 million and $16.9 million for the quarters ended March 31, 2024 and 2023, respectively.
• Research and development expenses were $17.0 million and $10.2 million for the quarters ended March 31, 2024 and 2023, respectively. The increase in expense was primarily due to increased headcount and clinical expense related to firmonertinib.
• General and administrative expenses were $3.7 million and $1.9 million for the quarters ended March 31, 2024 and 2023, respectively. The increase in expense was primarily due to expenses related to expanding the infrastructure necessary for operating as a public company.
• Net loss was $17.4 million and $12.2 million for the quarters ended March 31, 2024 and 2023, respectively.  

About ArriVentArriVent is a clinical-stage biopharmaceutical company dedicated to the identification, development, and commercialization of differentiated medicines to address the unmet medical needs of patients with cancers. ArriVent seeks to utilize its team’s deep drug development experience to maximize the potential of its lead development candidate, firmonertinib, and advance a pipeline of novel therapeutics, such as next-generation antibody drug conjugates, through approval and commercialization.

About FirmonertinibFirmonertinib (formerly furmonertinib) is an oral, highly brain-penetrant, and broadly active mutation-selective epidermal growth factor receptor (EGFR) inhibitor active against both classical and uncommon EGFR mutations, including PACC and exon 20 insertion mutations. In March 2021, firmonertinib was approved in China for first-line advanced non-small-cell lung cancer (NSCLC) with EGFR exon 19 deletion or L858R mutations and for patients with previously treated locally advanced or metastatic NSCLC with EGFR T790M mutation, otherwise known as EGFR classical mutations.

In October 2023, firmonertinib was granted U.S. Food and Drug Administration Breakthrough Therapy Designation for the treatment of patients with previously untreated locally advanced or metastatic non-squamous NSCLC with EGFR exon 20 insertion mutations.

Firmonertinib is currently being studied in a global Phase 3 trial for first-line NSCLC patients with EGFR exon 20 insertion mutations (FURVENT; NCT05607550) and in a global Phase 1b study evaluating firmonertinib in patients EGFR PACC mutations (FURTHER; NCT05364043).  In addition, firmonertinib is also being studied in a clinical combination study targeting advanced or metastatic NSCLC patients with EGFR classical mutations, in partnership with InnoCare Pharma.

About EGFR mutant NSCLCGlobally, lung cancer is the leading cause of cancer-related deaths among men and women. NSCLC is the predominant subtype of lung cancer, accounting for approximately 85% of all cases. Mutational activation of the EGFR is a frequent and early event in the development of NSCLC. EGFR mutations are divided into classical and uncommon. EGFR exon 20 insertion mutations are a group of uncommon EGFR mutations and constitute approximately 9% of all EGFR mutations.  PACC mutations are another group of uncommon EGFR mutations and represent approximately 12% of all EGFR mutations. Patients with NSCLC whose tumors harbor uncommon EGFR mutations have significantly lower life expectancy with available therapies and represent an area of unmet medical need.
